Investigating pH, ammonia, and nitrate content in West Lake


Research Question:


Does the nitrate and phosphate levels reflect the amount of pollution in West Lake?


Equipment:

- transportation

- pH paper
- a turbidity kit
- a freshwater test kit (ammonia kit & nitrate kit)
- 1 marker pen

By investigating the pH, ammonia, and nitrate content we can analyse the pollution level in the lake.


Method:

  1. Locate a water source. Collect 5 sample of the water
  2. The 10 bottles of water are then tested for their acidity using the pH paper/probe and their turbidity is also tested using the turbidity meter.
  3. The fresh water test kit is used to test for the water’s ammonia and nitrate content.
